Abstract (en)
Disclosed is a water-repellent nonwoven fabric made of a melt-blown fiber having a single filament denier of 0.005 to 2.0, wherein the fiber packing ratio is 5 to 70% and the water pressure resistance index is 400 to 2,000 mmh<sub>2</sub>0. The nonwoven fabric is used for an oil-water separating filter having a permeability to oil and non-permeability to water. A composite fabric comprising a combination of the nonwoven fabric and an air-permeable knitted or woven fabric laminated and integrated with at least one surface of the nonwoven fabric is useful as an air permeable and water repellent fabric.
